Cardiovascular treatment gaps: closing, but slowly

Area of Science:

• Cardiology
• General Practice
• Public Health

Background:

• Cardiovascular disease remains a leading cause of mortality globally.
• Effective primary prevention strategies are crucial for reducing cardiovascular events.
• Understanding prescribing trends in primary care is essential for optimizing cardiovascular risk management.

Purpose of the Study:

• To analyze trends in cardiovascular preventive medication prescribing in New Zealand primary care between 2000 and 2003.
• To assess whether prescribing patterns aligned with estimated cardiovascular risk levels.

Main Methods:

• Utilized data from the Dunedin Royal New Zealand College of General Practitioners Research Unit database.
• Included demographic, risk factor, and prescribing data for adults aged 45+ (men) and 55+ (women).
• Analyzed electronic clinical notes from general practices between 2000 and 2003.

Main Results:

• Cardiovascular risk could only be estimated for one-third of the population due to missing data.
• In 2000, 28% of those with vascular disease and 14-16% with >5% 5-year risk received both blood pressure and cholesterol medication.
• Treatment rates for patients with >10% 5-year risk increased by ~4% annually; those with 5-10% risk increased by ~3% annually.

Conclusions:

• A significant gap in cardiovascular medicine treatment in primary care narrowed between 2000 and 2003 but persisted.
• Evidence suggests modest targeting of treatment to estimated cardiovascular risk.
• Ongoing collection and analysis of prescribing data are vital for monitoring and improving cardiovascular risk assessment and management strategies.
